In the past the role of mechanical resistance has been relatively neglected in agronomic studies, probably because of the academic separation of "soil mechanics" in schools of engineering from "soil physics" in schools of agriculture. When applied to agronomy, engineering theories of soil mechanics need to be modified to place more emphasis on the compressibility of the soil, and to be combined with a knowledge of the mechanics of plat growth. The evidence presented in this review suggests that mechanical resistance should be regarded as having a widespread influence on the growth of roots and underground shoots, rather than as a factor that operates only in unusually strong soils. |
